Title: Method and equipment for modeling color imaging device and storage medium
Inventor: WALKER DOUGLAS G
IPC: H04N1/46
Filed: 2000-02-22
Abstract: PROBLEM TO BE SOLVED: To exactly extend a model until an area in which measured data cannot be obtained by deciding gradient at each point selected by using a lower order model, and applying a high order model to the measured value and the gradient value. SOLUTION: A measured value (XYZ) and device data (RGB) are obtained (42), and a low order model is formed as a conventional manner, by using measured data (44) so that a model covering a non-measurement region can be formed. Then, a high order model is created (46), and extended to the non- measurement area. This model can be used for generating a device profile next (48). A polynomial model is extended by using the low order model of the device, such as a linear model for deciding or predicting gradient at a target point. The extended polynomial model is obtained by applying a model (that is, a curve) to the gradient and the measured point. That is, a curve which can be applied to the measured data point and provided with the desired gradient at the target point can be obtained.
